AUGUST F. SUCKOW, OF CHICAGO, ILLINOlS, ASSIGNOR OF ONE-HALF TO EDWARDJ. MELICH,

OF CHICAGO, ILLINOIS.

LEAF-TURNER.

Specification of Letters Patent.

Patented July 9, 1907.

To all whom it may concern:

Be it known that I, AUeUs'r F. SUCKOW, a citizen of the United States,and a resident of Chicago, in the county of Cook and State of Illinois,have invented certain new and useful Improvements in Leaf-Turners, ofwhich the following, when taken in connection with the drawingaccompanying and forming a part hereof, is a full and completespecification sufficient to enable those skilled in the art to which itpertains to understand, make, and use the same.

This invention relates to leaf turners which are principally used toturn the leaves of sheet music.

The object of the invention is to obtain a leaf turner of simpleconstruction, containing but few parts, not easily broken or gotten outof order; and by means of which a limited number of leaves can be turnedin either direction, that is, forward or backward.

I have illustrated a leaf turner embodying my invention in the drawingreferred to wherein Figure 1 is a front elevation of the leaf turner.Fig. 2 is a perspective of a key, a horizontal tube, and a springforming elements in the leaf turner. Fig. 3 is a perspective of avertical tube and a head secured on the lower end thereof, forming anelement of the leaf turner, and Fig. 4 is a top plan view of a part ofone of the horizontal tubes and wire therein forming elements in theleaf turner, showing a vertical tube in section and the head secured tothe lower end of the tube.

A reference letter applied to designate a given part is used to indicatesuch part throughout the several figures of the drawing wherever thesame appears.

A is the base of the leaf turner.

B, B, and C, C are respectively journal bearings.

D, D, are horizontal rods or wires rotatably mounted in bearings B, B.

E, E, are tubes rotatably mounted on rods or wires D, D, respectively.

F, F, and G, G, are springs. One end of the spring F is attached to apin d on one of the rods or wires D, D, and the other end of such springis attached to base A; and one end of a spring G is attached to pin 6 onone of the tubes E, E, and the other end of such spring is attached tobase A. Springs F and G yieldingly hold the rods or wires D, D, and thetubes E, E, in the position thereof illustrated in Fig. l of thedrawing.

II, E, H H are keys secured to rods D, D; and I, I, 1 ,1 are keyssecured to tubes E, E. On depression of a key of the H or I series acorresponding rod D or tube E is turned and on releasing the depressedkey it (and the rod or tube on which it is secured) is returned to itsinitial position by the corresponding spring F or Gr.

.T, K, are pins respectively secured in rods and tubes D and E.

L, L, L are tubes rotatably mounted in bearings C, O.

L may be a tube or a red, as preferred.

M, M, M M are arms respectively secured to tubes L, L L L and m, m, m mare spring catches on arms M, M, M M respectively.

N, N, and O, O, are washers.

P, P, are heads secured on the lower ends of tubes L, L, L and Lrespectively. Heads P, P, are substantially duplicates and each thereofis preferably provided with the CLllVOd. shoulders 12, p.

p is the back of head P with which the pins .1 and K alternately come incontact in the operation of the machine.

The manner of operation of the device is as follows;- Assuming the armsM, M, M and M to be in the position in which they are illustrated inFig. 1, and any one of such arms is to be moved. Arms M, M, being on theright hand side, as viewed, may be singly or jointly moved over to theleft hand side, as viewed, by depressing keys I or I. That is, if key Iis depressed the arm M is moved over to the right side, carrying aheadof it the arm M, which is, as illustrated, in front of arm M. If the keyI is depressed the arm M, being the front arm of arms M, M, is moved tothe left side. When arm I is depressed pin K thereon is turned againstthe head P adjacent thereto thereby tiuning the tube L, such head Pbeing rigidly secured to such tube L, and as the tube L turns such pin Kcomes into contact with the curved face 1) adjacent thereto, therebycontinuing the turning movement of the tube L, and as the key I isfurther depressed the pin Kis brought into contact with the back 19 ofsuch head P, thereby turning the tube L one half of a revolution. Whenthe key I is released it is returned to its initial position by thespring a as hereinbefore described. To turn any one of the arms M M onthe right side of Fig. 1 to the left side thereof, one of the keys H His depressed and thereby the corresponding one of the pins .T, J isturned against the head P adjacent thereto. The action of any pin J onthe head P adjacent thereto, when a corresponding key is depressed, isidentical with the action of the pin K on the head P adjacent theretowhen the key corresponding to such pin K is depressed, but turning thehead in the opposite direction.

The several tubes L, L, L and rod L are of suillcient length to permitthe sheet whereof the leaves are to be turned by the device to beattached to the spring catches m, m, m and m and come between suchspring catches and the base A.

When the device is used for turning music on a piano the base A isrigidly secured to the piano by any suitable means, or such base is madeof metal of suflicient Weight to rest on the piano without beingoverturned when a given key is depressed. When the base is secured tothe piano screws a, a, may be used for such purpose.

1. An upright rotatable shaft, an arm on the upper end of the shaft, anda head on the lower end thereof, a shaft and a tube on the shaft, suchtube and shaft rotatably mounted at right angles to the upright shaft, apin fixed to the shaft and a pin fixed to the tube on the shaft, suchpins located adjacent to the head, keys fixed to the shaft and tube,respectively, and means to yieldingly maintain the keys in an initialposition, substantially as described.

2. The combination of a series of upright tubes arranged one within theother to permit turning of any one thereof, an arm secured to the upperend of each of such tubes and a head secured to the other end of eachthereof, a plurality of series of keys, each series provided with a keycorresponding to a tube of the series of tubes, a plurality of series ofpins arranged with a pin of both series adjacent to each head, suchseries of pins corresponding to the series of keys, and connectionsbetween each of the pins of one series and a key of a correspondingseries; substantially as described.

3. The combination of a series of upright tubes arranged one within theother to permit turning of any one thereof, an arm secured to the upperend of each of such tubes and a head secured to the other end of eachthereof, a plurality of series of keys, each series provided with a keycorresponding to a tube of the series of tubes, a plurality of series ofpins arranged with a pin of both series adjacent to each head, suchseries of pins corresponding to the series of keys, connections betweeneach of the pins of one series and a key of a corresponding series, andmeans to yieldingly maintain the keys in an initial position;substantially as described.

l. A series of upright rotatable shafts consisting of a rod and tubesconcentric to the rod, an arm on the upper end of the respective uprightshafts, and a head on the lower end thereof, each of such heads providedwith curved portions on corners adjacent to the rear face of such'head,shafts and a tube on the shafts, respectively such tubes and shaftsrotatably mounted at right angles to the upright shafts, a pin fixed toeach of the shafts and a pin fixed to each of the tubes on the shafts, apin of both series of pins located adjacent to the head to contactsuccessively with the side thereof, a curved portion and the rear faceof such head when the corresponding tube or shaft is turned, keys on theshafts and tubes, respectively, and means to yieldingly maintain thekeys in an initial position, substantially as described.

5. A base, a series of upright concentric shafts rotatably mounted onthe base, an arm on the upper end of the respective upright shafts, anda head on the lower end thereof, each of such heads provided with curvedportions on corners adjacent to the rear face of such head, shafts and atube on the shafts respectively, such tubes and shafts rotatably mountedon the base at right angles to the upright shafts, pins fixed to theshafts and tubes thereon, respectively, such pins each located adjacentto one of the heads to contact with the side, a curved portion and arear face of such head when the corresponding tube or shaft is turned,keys on the shafts and tubes, respectively, and means to yieldinglymaintain the keys in an initial position, substantially as described.
